Sriracha Chicken with Scallions

"I have adapted this recipe from a buffalo wing recipe. I was looking for something to cook with chicken, scallions, and Sriracha sauce with an Asian flavor. After about a year of tinkering, this is what I came up with.
It can be tweaked to accommodate personal taste on spiciness. Level of heat is akin to hot wings, maybe a step hotter. Everything in this recipe can be changed to suit personal tastes. Serve with steamed rice and any other side dishes you wish.
This is how I like to make it for my desired level of spicy.
I would love any feedback and information on adaptations that have worked. Thanks!"

Directions

Coat the bottom of a skillet with vegetable oil and place over medium heat. Saute chicken in the hot oil until no longer pink in the center, 5 to 10 minutes. Add rice vinegar, soy sauce, mustard, chile oil, and Sriracha sauce, adding in exact order and waiting 1 minute between each addition for ingredient to layer.
